Note: count the number of reels of old chain; cheap at IGH and not deformed teeth on the chainring and cassette etc ... including single pinion. Old chain cut ... bolt cutters etc.; clean all teeth and new Fit chain; cut to length of the old chain. The fact is that only the chain links were lengthened and remains to be demonstrated no wear on the chainrings. I do not mean the cyclists with rusty dry chains that need to learn still care. Chain lock connects the two ends and immediately provided the chain well lubricated; rather regularly the chain maintain muster etc as a thick oil; I use graphite oil or even MOS2; days on it with sewing machine oil; So mixture. You have the circuit-Nabenschaltung- hardly readjust and the chain stops again at least 3 years 3 years with no switching problems in the 7-speed Nexus. Garantiert- this you have to wait, however. Then soon.
